Question

我试图使用Apollo客户端，我遇到了一些问题，将其放入带有redux的react starter套件中。 https://github.com/kriasoft/react-starter-kit/tree/feature/redux

尝试使用此处的技巧：http://dev.apollodata.com/react/server-side-rendering.html

但是我收到了错误

warning.js:36Warning: React attempted to reuse markup in a container but the checksum was invalid. This generally means that you are using server rendering and the markup generated on the server was not what the client was expecting. React injected new markup to compensate which works but you have lost many of the benefits of server rendering. Instead, figure out why the markup being generated is different on the client or server:
 (client) </div></header><div data-reactid="19">Lo
 (server) </div></header><div class="Home-root-2IM

这是我的实施

// server.js
...
const component = (
  <App context={context}>
    <ApolloProvider client={context.client} store={context.store}>
      {route.component}
    </ApolloProvider>
  </App>
);


await getDataFromTree(component);

data.children = ReactDOM.renderToString(component);
data.style = [...css].join('');
data.scripts = [
  assets.vendor.js,
  assets.client.js,
];
data.state = context.store.getState();
if (assets[route.chunk]) {
  data.scripts.push(assets[route.chunk].js);
}

const html = ReactDOM.renderToStaticMarkup(<Html {...data} />);
res.status(route.status || 200);
res.send(`<!doctype html>${html}`);
...

和客户方

// client.js
...
const component = (
  <App context={context}>
    <ApolloProvider client={context.client} store={context.store}>
      {route.component}
    </ApolloProvider>
  </App>
);

appInstance = ReactDOM.render(
 component,
  container,
  () => onRenderComplete(route, location),
);
...


// Home.js

class Home extends React.Component {
  static propTypes = {
    collections: PropTypes.arrayOf(PropTypes.shape({
      id: PropTypes.string.isRequired,
      title: PropTypes.string.isRequired,
      subtitle: PropTypes.string.isRequired,
      photo: PropTypes.string,
    })).isRequired,
  };

  render() {
    const props = this.props;
    const { loading, allCollections } = props.data;

    if (loading) {
      return <div>Loading</div>;
    } else {
      return (
        <div className={s.root}>
          <div className={s.container}>
            <h1 className={s.title}>Collections</h1>
            <ul>
              {allCollections.map((collection) =>
                <li key={collection.id}>
                  <h3>{collection.title}</h3>
                  <img src={collection.photo} width="200"/>
                </li>
              )}
            </ul>
          </div>
        </div>
      );
    }

  }
}

Home.propTypes = {
  data: PropTypes.shape({
    loading: PropTypes.bool.isRequired,
    allCollections: PropTypes.array,
  }).isRequired,
};


const HomeWithStyles =  withStyles(s)(Home);
const HomeWithData = graphql(getQuery)(HomeWithStyles);
export default connect()(HomeWithData);

所以答案是没有为apollo客户端数据设置初始状态

// client.js 

let apolloOptions = {
  ssrMode: false,
  initialState: { apollo: { data: window.APP_STATE.apollo.data } }, // NOT __APOLLO_STATE__ as set in some of the examples online 
  ssrForceFetchDelay: 500,
  networkInterface: createNetworkInterface({
    uri: window.APP_STATE.runtime.graphUri,
  }),
  opts: {
    credentials: 'same-origin',
  },
};
const client = new ApolloClient(apolloOptions);

在服务器上

// server.js

...
// data.state gets rendered by the server to client as APP_STATE
data.state = context.store.getState();
data.state.apollo = client.store ? client.store.getState().apollo : null;
...

使用apollo客户端与反应启动器套件同构时获取校验和无效警告
